在Mac上安裝ImageMagick，經過im4java調用

在Mac上我是經過 Homebrew來進行ImageMagick的安裝的

一、安裝brew 

$ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)」

二、安裝ImageMagick 

$ brew install imagemagick

三、起初是想經過JMagick來實現的，可是考慮到調用Im4java的優點和在Mac下安裝的繁瑣，選擇了Im4java。

「Advantages of im4java: the interface of the IM commandline is quite stable, so your java program (and the im4java-library) will work across many versions of IM. im4java also provides a better OO interface (the "language" of the IM-commandline with it's postfix-operation notation translates very easily into OO-notation). And most important: you can use im4java everywhere JMagick can't be used because of the JNI hazard (e.g. java application servers).」

四、實現

ProcessStarter.setGlobalSearchPath("/usr/local/bin/");
			IMOperation op = new IMOperation();
			op.addImage("/Users/liyinjun/Desktop/12.jpg");
			op.resize(100,200);
			op.addImage("/Users/liyinjun/Desktop/new_12.jpg");
			ConvertCmd convert = new ConvertCmd();
			try {
				convert.run(op);
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IM4JavaException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
